In the system debugging operation phase, if the following anomalies are found:(means the gas is poor !)
1) The refrigeration capacity of the system is obviously insufficient, and the refrigerant is not concerned with other abnormalities after inspection;
2) The system dryer filter or expansion valve is clogged, and the blockage is yellow-yellow waxy or black sludge-like foreign matter, so pay attention to the refrigerant;
3) High and low pressure or temperature anomalies occur during system operation, or the system balance pressure is abnormal during shutdown (can refer to the refrigerant temperature and pressure characteristics table), and attention should be paid to the refrigerant. When these anomalies occur, it is recommended to extract refrigerant from the system for purity testing to check for the risk of inferior refrigerants. During this time, it is recommended to vent the compressor side refrigerant or to release the system-wide refrigerant to avoid potentially inferior refrigerant contact with the compressor and damage the compressor.
Once a unit component or compressor failure is discovered due to chemical contamination caused by inferior refrigerants, the unit that used the same source of refrigerant at that site (even if the unit is still functioning properly) will need to be replaced with refrigerant. Because the effects of hazardous chemicals in inferior refrigerants are sometimes slow, they can cause system failure after a long period of use.
